Did you have to install the kernel extension or did it work out of the box?

Interestingly enough, some cards don't require any hand-holding and work without it.

I guess I'll pass on the DVI HDMI adapter approach because I can't use it for 3D gaming in Windows. Will check if the audio works because I haven't tested it much since I installed it. Then I'll try the script. Is this going to cause any instability problems or something like that using kernel extension? I don't want to touch system files.

UPDATE: WORKS LIKE A CHARM... GETTING 5.1 SURROUND SOUND.

Update #2: When you unplug the HDMI cable, you loose all sound. No audio devices so you have to reboot. Not a big deal.

Call me dumb
I use my 4.1 flashed to 5.1 pro for very little, its filling the roll of media server.
Still have the original GT120 card installed.
I do recall reading some time back that this card did not support audio via display port. Well I figured this was something new and i'd give try it.
Ran the command then rebooted, Now I am in a reboot loop as it tries to load.
I can get in via safe mode

Someone have an easily way to undo remove this extension?

update: decided to try the display port to HDMI and it completed the boot fine.
No audio, then shut down and re-tried the dvi to hdmi, again completed the boot this time fine, no audio from that gt120.
Not sure why after booting safe mode and exiting it now boots fine with the extension.

Nonetheless, anyone want to help with the removal undo this mod?

Sorry for the late response! I'm currently overseas. Unfortunately, this extension only works with cards that support outputting audio over DVI/HDMI.

I've updated my original post with instructions on how to remove the extension. Again, I'm sorry for the trouble!

My 2009 4-core Mac Pro uses a modest, yet very capable, EVGA nVidia GT430 1TB HDMI/VGA/DVI graphics card, which can be found used for $30-45. Performance in an HTPC application is excellent, using an HDMI cable.

I'm using OS Mountain Lion 10.8.4. It works perfectly, with the 4,1 firmware upgraded to 5,1, though it works fine with 4,1 also. 5,1 will allow use of 1333MHz RAM, if needed, though the stock 1066MHz RAM is fine for the job.

Adding a $50 internal Blu-Ray reader/burner in place of the stock Superdrive is a 10 minute job, making for a fine HTPC rig, much cheaper than a loaded MacMini with similar specifications.
